my st185 is limited to about 125mph, and revs go no more than 5000rpm in 5th gear, how do i de-restict the car, also wat is the standard boost level set at and how do i go about increasing it by a bit.

many thanks in advance

Other than a after market computer I'm not sure how to remove the limiters, there will be a way though. If you want a cheap way to raise the boost I posted a topic "robbed of boost" that explains a bit about how you could for the cost of a metre of vacuum hose. I'm not sure if it works or how successful it would be but if you want to try... I havent had the time and the exhaust is on the "needs to be fixed list" but hey I can't see it not working. Let me know if you try it.
